View not clickable after translate in CoordinatorLayot

I have a ConstraintLayout wrapping my FABs section in the bottom right of the app. I use a layout and not only the buttons because I have more views all around the FABs (they are omitted in the example below, the real layout is more complex). The layout has a CoordinatorLayout as main parent. I have two FABs, one near to the other, when I click the first one the second animates and move up using ViewPropertyAnimations, then I click the second one and other views should appear. ISSUE IS: the translated FAB isn't clickable. I can click on it before the animation starts but not after translation.

not clickable fab

What I've found so far:

Can you help me to fix this?

Animation code

FloatingActionButton fab1 = requireView().findViewById(R.id.fab1);
FloatingActionButton fab2 = requireView().findViewById(R.id.fab2);

fab1.setOnClickListener(v -> fab2.animate().translationY(-200));
fab1.setOnLongClickListener(v -> {
    fab2.animate().translationY(0);
    return true;
});

fab2.setOnClickListener(v -> Toast.makeText(requireContext(),"click",Toast.LENGTH_SHORT).show());
Solution

  • The issue seems solved with constraintlayout:2.1.0
